I'm not a big believer in distance as an enhancer of love interest. I think that's a myth and typically results in one or both finding other lovers to do. Seen it way too many times up close and personal to WANT distance between one I want and myself. There is no standard distance in miles or blocks that fits the mold. "What sort of distance is better"? What does that mean? Don't really get what you're after with the question other than you sound like you want your space, and want her far enough away to not get in your way.

yesterday, my thought was on this distance, interesting that nothing I can think and not see it a day after. it was that two words in my language mibeda and imhabba or in English the root of this meaning is separation or hate and the other love or an act of arming or holding in arms in totality. If in distance you include thing of nature its image brings you into your and hers conscious pleasing to real live that you joyful to the heart and harm to no one then that distance is right. the distance, the relationship between two person and the cause of that exchanges brings what - more life or death, see this in your heart to tell you and not your mind and it would tell you truth and you would see the real fruit that makes joy to be together all the time not just work and sex and giving money and material for the death. you would repent it if fall to a lie as your Karma.
